We now call those modeling lamps in our big stobes. I think that the analogy is even better considering your intentions.I personally feel strongly that high sensitivity is the correct path and that small ported woofers in a MTM box will fall short of...

You can build DSET for anything. DSET concept does not imply any topology but recognition of purpose and accommodation of a topology for the purpose. Generally the 93dB sensitivity is not something that I would attack with SET, unless you use SET aro...

Romy:Thank you for the reply.  First, a correction:  I have a pair of TAD 1201.  The MTM idea would utilize other drivers, such as the LE-8, 2118, etc.  I'm certainly not against buying another pair of TAD, however.The 1201 w...

of MTM arrangement of two TAD 1201 in <100 Hz Horn ? I assume they would both work in the same frequency range . Also JBL LE8 is only 89 db driver and it doesn't look like it can take any power . Difference in efficiency within the channels would ...

I think I remember James saying that the center channel should be the strongest channel, and if this is the case he might not scrub the full 6 dB from the L+R "sum". James did say the device "corrects" for mistakes embedded in the original, wrongly-c...

Greg, I see a regions of concerns that you might contemplate. TAD 1201 might be good driver but how useable would be the 200/300-800/1000 range? Let pretend that you end up with 250Hz, then what next? You will introduce a bottom octave section but t...

Looking at the drivers, and the range of adjustments, it appears that Wilson have done some things that make more sense than usual, at least to me.  The MTM drivers can easily be set for "time alignment", which should help to cope with Wilson's "noto...
